Hi
I'm trying to simulate the channel capacity with BPSK inputs in energy per bit to noise power spectral density ratio(Eb/N0). The formula which I used is written at the end. As snr=rate*Eb/N0, which is correct in that formula for simulation?
1-I replace snr=(C/α)*Eb/N0 in that formula and solve a fixed point equation ?
2-I simulate C in snr e.g. snr=-1:20 db and then define Eb= snr-10log10(C/α) and plot the obtained C in Eb/N0 instead of snr?
I would be appreciated if you help me.
C=2α-2α∫sqrt(((1-α)snr/pi))×exp(-(1-α)snr(s-1)^2 )×log2(1+exp(-4(1-α)×snr×s)) ds
